Description

Technical Field

[0001] This utility model relates to the field of dairy processing technology, and in particular to a semi-homogenizing device for raw materials after fresh milk separation. Background Technology

[0002] After separation and filtration, raw milk can be effectively separated into three raw materials: skim milk, light cream, and concentrated skim milk. Although the skim milk, light cream, and concentrated skim milk obtained after separation and filtration have different components and properties, in the production of many dairy products, they usually need to be mixed in a certain proportion and then homogenized.

[0003] In traditional dairy production processes, raw milk is separated into skim milk, cream, and concentrated skim milk. These are typically mixed in a specific ratio and then homogenized. However, due to differences in physical properties such as viscosity, density, and fat particle size among skim milk, cream, and concentrated skim milk, the homogenization effect is poor, resulting in stratification and sedimentation. This affects the quality and stability of the final dairy product. Furthermore, the process of mixing in a specific ratio and then homogenizing is complex, involving multiple pieces of equipment, increasing production costs and management difficulty, and reducing work efficiency.

[0004] Therefore, a semi-homogenizing device for raw materials after fresh milk separation is proposed to solve the technical problem of poor homogenization effect when skim milk, light cream and concentrated skim milk are mixed and homogenized in the above proportion. Utility Model Content

A first pipe, a homogenizing pump, and a second pipe are sequentially connected on the raw material discharge pipe along the raw material flow direction. A semi-homogenizing component is installed on the first pipe.

[0008] The semi-homogeneous assembly includes a jacket, an inlet pipe, and an outlet pipe. The jacket is disposed on a first pipe, and the inlet pipe and the outlet pipe are both connected to the jacket. Several impellers are disposed inside the first pipe along its length. Grooves are formed on the inner wall of the first pipe at positions corresponding to the impellers. The impellers are rotatably connected in the grooves. The spacing between two adjacent blades on the several impellers decreases sequentially along the raw material flow direction.

[0009] Preferably, a plurality of heat-conducting units are provided on the first tube along its length direction. Each heat-conducting unit includes a plurality of heat-conducting needles. The heat-conducting needles are disposed on the first tube and their two ends pass through and extend into the jacket and into the first tube, respectively.

[0010] Preferably, the heat-conducting needle is any one of copper needle, aluminum alloy needle, or tungsten alloy needle.

[0012] Preferably, a mounting groove is provided on the outer periphery of the pressure plate near its bottom surface, and a rubber sleeve is provided in the mounting groove.

[0013] Preferably, the storage cylinder is a hollow cylinder with a missing top surface, and the storage cylinder is any one of a copper cylinder, an aluminum alloy cylinder, or a tungsten alloy cylinder.

[0016] Preferably, the top surface of the pressure plate is connected to the output shaft of the cylinder, and a support frame is provided on the cylinder, and the support frame is connected to the second connecting part.

[0017] Preferably, the inner bottom wall of the storage cylinder is a tapered surface with an inner diameter that gradually decreases from top to bottom.

[0018] The present invention adopts the above technical solution and has the following technical effects compared with the prior art:

[0019] (1) The raw material after fresh milk separation is used in a semi-homogenizing device. Through the semi-homogenizing components, hot water flows in the jacket to heat the cream in the first tube. The increased temperature makes it easier for the fat particles in the cream to be refined during the homogenization process, which improves the subsequent homogenization effect. At the same time, several impellers are used. When the cream flows through the first tube, the impellers start to rotate, providing high shear force to the flowing cream, which breaks down the fat and solid suspension in the cream and achieves further dispersion. After the cream is pre-treated, it is then used with a homogenizing pump to make the fat particles in the cream smaller, thereby achieving pre-homogenization of the cream to improve the homogenization effect when the cream is mixed and homogenized with skim milk and concentrated skim milk in the later stage.

[0020] (2) The raw material after fresh milk separation is used in a semi-homogenization device. Through the cooperation of the semi-homogenization component and the homogenization pump, the cream can be pre-homogenized during the transportation process, thereby refining the fat particles in the cream. This allows the cream to be directly mixed and homogenized with skim milk and concentrated skim milk in the subsequent process, thus improving work efficiency.

[0021] (3) The raw material after fresh milk separation is used in a semi-homogenizing device. After adding the emulsifier for homogenization to the storage cylinder, the emulsifier is injected into the first tube through the guide pipe by the cylinder and the pressure plate. After the emulsifier combines with the cream in the first tube, the tension of the cream is reduced and the subsequent homogenization effect is improved.

[0022] (4) The raw materials after fresh milk separation are used in a semi-homogenizing device. The material of the storage cylinder is a metal with good thermal conductivity. The emulsifier in the storage cylinder is heated by hot water in the jacket. After heating, the emulsifier can accelerate the emulsification reaction, improve the homogenization efficiency, and reduce the time required for homogenization. Attached Figure Description

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0032] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0033] Example 1:

[0034] Please see Figure 1-5 In this embodiment, a semi-homogenizing device for raw materials after fresh milk separation includes a raw material discharge pipe 200 disposed on a tank 100. A first pipe 300, a homogenizing pump 400, and a second pipe 500 are sequentially connected on the raw material discharge pipe 200 along the raw material flow direction. A semi-homogenizing component 600 is disposed on the first pipe 300.

[0035] The semi-homogeneous component 600 includes a jacket 601, an inlet pipe 602, and an outlet pipe 603. The jacket 601 is disposed on the first pipe 300. The inlet pipe 602 and the outlet pipe 603 are both connected to the jacket 601. Several impellers 606 are disposed inside the first pipe 300 along its length. Grooves 607 are formed on the inner wall of the first pipe 300 corresponding to the impellers 606. The impellers 606 are rotatably connected in the grooves 607. The spacing between two adjacent blades on the several impellers 606 decreases sequentially along the raw material flow direction.

[0036] In application, the whipped cream in tank 100 leaves tank 100 through raw material outlet pipe 200 and enters the first pipe 300. Simultaneously, external hot water enters the jacket 601 through water inlet pipe 602. The heat of the hot water is first conducted to the jacket 601 and the first pipe 300, heating the whipped cream in the first pipe 300. The increased temperature makes the fat globules in the whipped cream softer and easier to break. After the temperature rises, the hardness of the fat globules decreases, making them easier to refine during the homogenization process. At the same time, as the whipped cream flows through the first pipe 300, several impellers 606 are subjected to the kinetic energy and pressure of the whipped cream flowing through the first pipe 300. The impeller 606 is driven to rotate within the groove 607. During the rotation of several impellers 606, a high shear force is provided to the flowing cream, causing the fat and solid suspensions in the cream to be broken up, thus further dispersing the cream. After the cream in the first tube 300 undergoes preliminary treatment by the semi-homogenizing component 600, it flows to the homogenizing pump 400. The homogenizing pump 400 homogenizes the cream, making the fat particles in the cream smaller. By pre-homogenizing the cream in the above manner, the fat particles in the cream can be effectively refined, thereby improving the homogenization effect when the cream is homogenized with skim milk and concentrated skim milk in the future.

[0037] It should be noted that light cream has a high fat content, and the size and distribution of fat particles significantly affect the uniformity of light cream, skim milk, and concentrated skim milk during homogenization. By pre-homogenizing the light cream during transportation, the fat particles in the light cream can be refined into uniform micro fat globules. These refined fat particles help the light cream to better combine with skim milk and concentrated skim milk during subsequent homogenization, thereby improving the quality of the final dairy product.

[0038] It should be noted that the spacing between two adjacent blades of impeller 606 is set to decrease sequentially along the raw material flow direction, so that the cream in the first tube 300 can be dispersed step by step during flow, which increases the non-uniformity of the cream flow and generates strong turbulence and shear force. Under the shear force of several impellers 606, the cream helps to break down larger fat globules and redisperse them into smaller fat particles, thus achieving pre-dispersion of the cream. This allows the fat particles to be effectively refined when the cream is homogenized by homogenizer pump 400.

[0039] It is known that the working principle and usage of the homogenizer 400 are well known to those skilled in the art, and will not be described in this embodiment.

[0040] Furthermore, a plurality of heat-conducting units 608 are provided on the first tube 300 along its length direction. Each heat-conducting unit 608 includes a plurality of heat-conducting needles 609. The heat-conducting needles 609 are provided on the first tube 300 and their two ends pass through and extend into the jacket 601 and the first tube 300, respectively.

[0041] Furthermore, the heat-conducting needle 609 is any one of a copper needle, an aluminum alloy needle, or a tungsten alloy needle; preferably, the heat-conducting needle 609 in this application is a copper needle.

[0042] Understandably, the heat-conducting needle 609 is made of copper. Copper needles have a high thermal conductivity, which allows the heat from the hot water in the jacket 601 to be quickly transferred to the cream in the first tube 300, thereby causing the cream to heat up rapidly.

[0043] Example 2:

[0044] The basic content is the same as the embodiment, the difference is: Please refer to Figure 6-7 In this embodiment, a storage cylinder 610 is provided above the first pipe 300. The storage cylinder 610 is connected to the first pipe 300 through a guide pipe 611, and a one-way valve 612 is provided on the guide pipe 611. A pressure plate 613 that moves along its length is provided above the storage cylinder 610. The outer diameter of the pressure plate 613 is adapted to the inner diameter of the storage cylinder 610.

[0045] In application, the storage cylinder 610 is used to store emulsifier. When it is necessary to add emulsifier into the first tube 300, the cylinder 616 is activated. The cylinder 616 drives the pressure plate 613 to move closer to the guide tube 611. As the pressure plate 613 moves, it pushes the emulsifier in the storage cylinder 610 into the guide tube 611. The emulsifier enters the first tube 300 through the guide tube 611. After the emulsifier comes into contact with the cream in the first tube 300, it reduces the surface tension of the cream and improves the subsequent homogenization effect.

[0046] It should be noted that the one-way valve 612 can prevent the cream in the first tube 300 from flowing back into the storage cylinder 610 due to pressure when the emulsifier is introduced into the feed pipe 611. The one-way valve 612 is a common device in the prior art and will not be described in detail in this application. The outlet direction of the one-way valve 612 is facing the first tube 300.

[0047] Furthermore, a mounting groove 614 is provided on the outer periphery of the pressure plate 613 near its bottom surface, and a rubber sleeve 615 is provided in the mounting groove 614.

[0048] It should be noted that the rubber sleeve 615 improves the sealing performance between the pressure plate 613 and the storage cylinder 610, and can prevent the emulsifier in the storage cylinder 610 from overflowing.

[0049] Furthermore, the cross-sectional shape of the jacket 601 is an inverted T-shape. The jacket 601 includes a first connecting part 604 arranged horizontally and a second connecting part 605 arranged vertically. The first connecting part 604 and the second connecting part 605 are vertically connected. The first tube 300 is disposed in the first connecting part 604 and the storage cylinder 610 is disposed in the second connecting part 605.

[0050] Furthermore, the storage cylinder 610 is detachably fixed inside the second connecting part 605. The outer side of the storage cylinder 610 is provided with an external thread, and the second connecting part 605 is provided with a threaded groove corresponding to the external thread. The external thread and the threaded groove are threadedly connected, and the guide tube 611 is detachably connected to the storage cylinder 610.

[0051] It should be noted that when the pressure plate 613 is at its highest point, the distance between the pressure plate 613 and the second connecting part 605 is greater than the height of the storage cylinder 610. When the storage cylinder 610 needs to be cleaned later, the storage cylinder 610 can be rotated, and the storage cylinder 610 can be easily removed from the second connecting part 605 through the cooperation of the external thread and the thread groove.

[0052] It is known that the guide tube 611 is connected to the storage cylinder 610 by a threaded connection, and the guide tube 611 is located on the first tube 300; when it is necessary to remove the storage cylinder 610 from the second connection part 605, rotating the storage cylinder 610 will also separate the storage cylinder 610 from the threaded first tube 300.

[0053] Furthermore, the storage cylinder 610 is a cylinder with a hollow interior and a missing top surface. The storage cylinder 610 is any one of a copper cylinder, an aluminum alloy cylinder, or a tungsten alloy cylinder; preferably, the storage cylinder 610 is a copper cylinder.

[0054] It should be noted that the storage cylinder 610 is a copper cylinder with a high thermal conductivity. The heat from the hot water in the jacket 601 can be quickly conducted to the emulsifier in the storage cylinder 610, heating the emulsifier. After the emulsifier is heated, it enters the first tube 300, which can accelerate the emulsification reaction, improve the homogenization efficiency, and reduce the time required for homogenization.

[0055] Furthermore, the top surface of the pressure plate 613 is connected to the output shaft of the cylinder 616, and a support frame 617 is provided on the cylinder 616, and the support frame 617 is connected to the second connecting part 605. Specifically, the cylinder 616 is connected to the control unit.

[0056] It is understood that the control unit controls the output shaft of cylinder 616 to extend and retract at a constant speed, so that the pressure plate 613 moves at a constant speed in the storage cylinder 610, thereby realizing the quantitative feeding of emulsifier; the control unit and its working principle are well known to those skilled in the art, and will not be described in this embodiment.

[0057] In one specific embodiment, the inner bottom wall of the storage cylinder 610 is a tapered surface with an inner diameter that gradually decreases from top to bottom.

[0058] It is known that the bottom wall of the storage cylinder 610 is conical. The conical shape allows the emulsifier in the storage cylinder 610 to enter the feed pipe 611 more quickly and eventually enter the first pipe 300.

[0059] In summary, combining Figures 1 to 7 As shown, the working principle of the semi-homogenizing device for raw materials after fresh milk separation is as follows: The cream in tank 100 leaves tank 100 through raw material outlet pipe 200 and enters the first pipe 300. Simultaneously, external hot water enters jacket 601 through inlet pipe 602. The heat from the hot water is first conducted to jacket 601 and the first pipe 300, heating the cream in the first pipe 300. Increased temperature makes the fat globules in the cream softer and easier to break. After the temperature rises, the hardness of the fat globules decreases, making them easier to refine during the homogenization process. Simultaneously, as the cream flows through the first pipe 300, several impellers 606... Driven by the kinetic energy and pressure of the cream in the first tube 300, the impeller 606 is driven to rotate in the groove 607. During the rotation of several impellers 606, a high shear force is provided to the flowing cream, which breaks down the fat and solid suspension in the cream, achieving further dispersion of the cream. In addition, during the flow of the cream, the added emulsifier can accelerate the emulsification reaction and reduce the time required for homogenization. After the cream in the first tube 300 has undergone preliminary treatment by the semi-homogenizing component 600, it flows to the homogenizing pump 400. The homogenizing pump 400 homogenizes the cream, making the fat particles of the cream smaller.

[0060] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
